If you say Y here, it will be possible to remotely debug the
kernel using gdb. It is recommended but not required, that
you also turn on the kernel config option
CONFIG_FRAME_POINTER to aid in producing more reliable stack
backtraces in the external debugger. Documentation of
kernel debugger is available at http://kgdb.sourceforge.net
as well as in DocBook form in Documentation/DocBook/. If
unsure, say N.

This is a kgdb I/O module specifically designed to test
kgdb's internal functions. This kgdb I/O module is
intended to for the development of new kgdb stubs
as well as regression testing the kgdb internals.
See the drivers/misc/kgdbts.c for the details about
the tests. The most basic of this I/O module is to boot
a kernel boot arguments "kgdbwait kgdbts=V1F100"

This is the command string to send the kgdb test suite on
boot. See the drivers/misc/kgdbts.c for detailed
information about other strings you could use beyond the
default of V1F100.

This will add an extra call back to kgdb for the breakpoint
